Alternatively, it is precipitated by adding hydrofluoric acid to a lead(II) salt solution, or by adding a fluoride salt to a lead salt, such as potassium fluoride to a lead(II) nitrate solution, [4]
It appears as the very rare mineral fluorocronite.[5][6]

Two 25 mm × 25 mm × 140 mm PbF 2 scintillator crystals used in the Muon g−2 experiment.
Lead(II) fluoride is used in low melting glasses, in glass coatings to reflect infrared rays, in phosphors for television-tube screens, and as a catalyst for the manufacture of picoline.[3] The Muon g−2 experiment uses PbF 2 scintillators in conjunction with silicon photomultipliers.[7]
